Spray Booths
An Open-Front Dry Filter Spray Booth
The Bomaksan dry filter spray booth is an open-front booth that defines the painting area with its side panels and ceiling, and extracts air through a rear filter wall. Paint mist generated during application is carried by the booth airflow into the paint arrestor filter stages and captured at the source.
Booth dimensions are engineered around your workpiece size, application method and plant layout. Multi-stage paint arrest and front filter access allow easy maintenance and uninterrupted operation during colour changes.
Controlling paint mist and volatile organic compounds (VOC) at the source is critical for worker health, product quality and environmental compliance. For heavy paint loads, the water curtain spray booth is an alternative worth considering.
How the System Works
- Capture at the source: Paint mist generated during application is carried by the booth airflow to the rear extraction wall. The booth opening and air requirement are defined together with the process conditions.
- Dry filtration: The paint arrestor pre-filter and a suitable second stage capture the particle load. Media selection, filter change interval and pressure drop are evaluated together.
- Extraction and exhaust: Filter resistance, duct routing and exhaust conditions determine the fan selection; fan and ductwork are sized as one system.
- Fresh air balance: Extracted air is replaced with a controlled, filtered fresh air supply. System control is defined according to thermal conditions and room pressure requirements.
System Components
- Panel booth: side walls and ceiling enclose the working area; dimensions are defined by the workpiece
- Paint arrestor pre-filter: the replaceable first stage where the paint mist load is captured
- Second filter stage: arrestor media matched to the paint type for particles passing the pre-filter
- Rear extraction plenum: collects filtered air towards the fan connection
- Extraction fan: top-mounted fan selected for the required airflow, filter resistance and duct losses

- Small parts and touch-up: bench-top painting, sample work and local touch-up jobs
- Special applications: different part geometries, integration into existing lines and special process needs
Frequently Asked Questions
How are the booth dimensions determined?
The largest workpiece dimensions, application method and plant layout are evaluated together; internal booth dimensions and air requirement are defined per project.
How are the filters changed?
The paint arrestor stages are accessed from the front. Filter media is selected for the paint type and load; the change interval is planned together with pressure drop monitoring.
Does the booth also capture solvent vapours (VOC)?
Dry filter stages capture paint particles; particle capture and VOC control are separate matters. For solvent vapours, a separate treatment (such as an activated carbon module) is evaluated based on the paint content and emission load.
